    Comparison of surface roughness of sections cut by diamond, sapphire, and glass knives (1987)

    Notes: Low-angle chromium metal shadowing was used to compare the surface roughness of ultrathin sections cut with diamond, sapphire, and glass knives. Surface roughness was less on diamond-cut and sapphire-cut sections than on glass-cut sections, and was greater over tissue than resin, and greatest over red blood cells and mitochondria. Surface roughness contributed to image density variation and thereby lowered contrast and informational content of the sectioned tissue.

    Contamination of thin sections: Some observations on the cause and elimination of “embedding pepper” (1987)
    New York, NY : Wiley-Blackwell
    Journal of Electron Microscopy Technique 5 (1987), S. 59-63

    ISSN: 0741-0581
    Keywords: Electron microscopy ; Postsection staining ; Section contamination ; Life and Medical Sciences ; Cell & Developmental Biology

    Topics: Natural Sciences in General
    Notes: A method is described for eliminating a form of contamination called embedding pepper that appears in, or on, thin sections following poststaining in lead citrate. The pepper is present most often in the matrixes of mitochondria, peroxisomes, and red blood cells. Formation of pepper can be prevented by treating the section with 0.5 N HCl or 1.0% ethylenediaminete-traacetic acid (EDTA) for 1-5 min before staining in uranyl acetate or lead citrate.
